AME8827 Datasheet, PDF (1/16 Pages) Analog Microelectronics – Low Dropout 1A CMOS Regulator

AME
AME8827
Low Dropout 1A CMOS Regulator
n General Description
The AME8827 family of positive, CMOS linear regula-
tors and provide low dropout voltage (340mV @ 1A) and
excellent PSRR, thus making them ideal for power-sav-
ing systems. These rugged devices have both Thermal
Shutdown, and Current limit to prevent device failure un-
der the "Worst" of operating conditions.
The AME8827 is stable with an output capacitance of
4.7µF or larger.
